Description

TECHNICAL FIELD

The present invention relates to eyeglasses and more particularly to eyeglasses which can be easily put on and off with one hand, and which are capable of preventing shifts of the eyeglasses when worn.

BACKGROUND ART

FIG. 8 is a perspective view showing conventional eyeglasses.

As shown in FIG. 8, conventional eyeglasses 50 include a pair of right and left lenses R, a frame body 51 supporting the lenses R, temple portions 55 mounted to both sides of the frame body 51 and pads 52 mounted to a central bridge of the frame body 51.

Conventional eyeglasses 50 are put on by holding respective temple portions 55 on both sides with one's hands and by putting them on corresponding right and left ears.

Accordingly, in case of the conventional eyeglasses 50, it is difficult to put them on using only one hand when the other hand is occupied or dirty.

In contrast thereto, eyeglasses of specific shapes including no temple portion on one side are being developed.

For instance, there are known eyeglasses in which a hair-fastening tool is mounted to a temple of the eyeglasses wherein the lens and the frame are supported by attaching the tool to one's hair (see, for instance, Patent Literature 1).

Advantageous Effects of Invention

In case of the eyeglasses according to the present invention, by providing only one side of the front frame portion as the temple portion while providing the other side as the abutting portion, the eyeglasses can be put easily on and off with one hand. Namely, they can be put on by putting the temple portion on an ear in a state in which the abutting portion abuts a side surface of a face.

Further, since the eyeglasses are fixed at three spots, that is, the temple portion, the pad portion and the abutting portion, it is possible to prevent shifts of the eyeglasses when worn.

In case of the eyeglasses according to the present invention, since the temple portion is formed with the picking portion along the longitudinal direction of the temple portion, the eyeglasses can be more easily put on by grasping the picking portion.

For instance, when the temple portion has a narrow rod-like shape, there is a drawback that the eyeglasses are randomly rotated around the temple portion when the temple portion is directly gripped, but this can be prevented by providing the picking portion and by grasping the picking portion.

In case of the eyeglasses according to the present invention, when the abutting portion is comprised of the base portion and the head portion, and has a T-like shape when seen from the side, it is of advantage that the base portion having a relatively small diameter can be easily mounted to the front frame portion, while it is of advantage that the head portion having a relatively large diameter can reduce pressure loading to the face when abutted to the side surface of a face.

Further, since the peripheral edge of the disk-like head on the opposite side of the base portion has a tapered shape, it is possible to restrict that the side surface of the face is scratched by the abutting portion even if the worn eyeglasses are shifted.

In case of the eyeglasses according to the present invention, when the abutting portion has a polygonal pillar-like shape extending in the longitudinal direction of the front frame portion, it is of advantage that the eyeglasses can be easily abutted in accordance with the shape of the side surface of the face.

In case of the eyeglasses according to the present invention, when the abutting portion is slidable along the front frame portion, it is possible to adjust the position of the abutting portion.

In case of the eyeglasses according to the present invention, when the end portion on the other side of the front frame portion has a J-like shape with its tip being folded back to the inside, the degree of freedom of the end portion on the other side of the front frame portion is improved. With this arrangement, the abutting portion can be reliably abutted in accordance with the shape of the side surface of the face.

In case of the eyeglasses according to the present invention, when the front frame portion is comprised of the supporting portion supporting the lenses, the first frame portion extending to one side of the supporting portion and the second frame portion extending to the other side of the supporting portion and the second frame portion has a loop-like shape, there will be no temple portion at the second frame portion while the first frame portion is formed with a temple portion, it is possible to equilibrate the entire weight balance by forming the second frame portion to have a loop-like shape.

At this time, when a tip end and a rear end of the second frame portion are inserted into the supporting portion, and the tip end or the rear end is slidable within the supporting portion, it is possible to adjust the position of the abutting portion by sliding the tip end or the rear end of the second frame portion.

In case of the eyeglasses according to the present invention, since the mounting portion is formed at the other side of the front frame portion and the external temple portion is freely attachable/detachable to and from the mounting portion, it is possible to add desired functions by attaching the external temple portion.

For instance, when the external temple portion is a temple portion with a monitor, it is possible to watch movies or the like through the monitor, and it is also possible to use the Internet by using a computer stored in the external temple portion through the monitor.

DESCRIPTION OF EMBODIMENTS

Preferred embodiments of the present invention will be explained in details while referring to the drawings as necessary. In this respect, identical elements are marked with identical reference signs in the drawings, and duplicated explanations will be omitted. Further, dimension ratios in the drawings are not limited to the illustrated ratios.

First Embodiment

FIG. 1(a) is a perspective view showing eyeglasses according to the first embodiment, and FIG. 1(b) is a plan view thereof.

As shown in FIG. 1(a) and FIG. 1(b), the eyeglasses 100 according to the first embodiment include a pair of right and left lenses R, a front frame portion 1 supporting the lenses R, a pad portion 2 mounted to the center of the front frame portion 1, a hinge portion 3 formed at an end portion on one side of the front frame portion 1, a temple portion 5 extending rearward from the hinge portion 3 and an abutting portion 10 formed at an end portion on the other side of the front frame portion 1 to project to the inside.

In case of the eyeglasses 100 according to the first embodiment, only one side of the front frame portion 1 includes the temple portion 5 via the hinge portion 3, and the other side does not have a hinge portion or a temple portion.

The front frame portion 1 is comprised of a supporting portion 1a, a first frame portion 1b extending from the supporting portion 1a to one side and a second frame portion 1c extending from the supporting portion 1a to the other side.

In this respect, the first frame portion 1b and the second frame portion 1c are left-right asymmetric.

While materials of the first frame portion 1b and the second frame portion 1c are not particularly limited here, it is possible to use, among others, titanium, titanium alloys or stainless steel. Among these, the materials are preferably β titanium or SUS304 which exhibit elasticity.

When the first frame portion 1b and the second frame portion 1c exhibit elasticity, it will be possible to expand the temple portion 5 to the outside while the abutting portion 10 is in a state in which it abuts the side surface of the face, and the eyeglasses can be more easily put on.

Further, since the abutting portion 10 or the temple portion 5 is pressed to the inside through restoring force of the first frame portion 1b and the second frame portion 1c, the worn eyeglasses will be more hardly shifted.

Moreover, since the lenses R are not fitted into the first frame portion 1b or the second frame portion 1c, it is easier to expand the first frame portion 1b and the second frame portion 1c to the outside.

In the front frame portion 1, the supporting portion 1a supports the pair of lenses R in the right and left direction by pinning.

The pad portion 2 is mounted at the center of the supporting portion 1a to face inside. In this respect, the pad portion 2 is a portion that is hooked to the nose when the eyeglasses 100 are worn, and known ones can be suitably used.

The first frame portion 1b is configured to extend from the supporting portion 1a along an upper surface of a lens R and to be bent rearward at substantially right angles upon exceeding the lens R, and the hinge portion 3 is formed at an end portion thereof.

Then, the temple portion 5 is mounted to the hinge portion 3 to be rotatable in the horizontal direction.

The temple portion 5 is configured to warp in the horizontal direction to extend along the contour of the side surface of the face, and a loop-like hook portion 5b to be hooked to an ear is formed at a rear end portion thereof. In this respect, the hook portion 5b has a shape which lower portion is warped to extend along the shape of the root of the ear.

Further, the temple portion 5 is formed with a picking portion 5a along the longitudinal direction thereof.

FIG. 2 is a perspective view showing the picking portion of the eyeglasses according to the first embodiment.

As shown in FIG. 2, the picking portion 5a has a broad width in the horizontal direction so as to enable easy picking with fingers, and has a concave lower side. Therefore, in case of the eyeglasses 100, the eyeglasses can be easily put on also with one hand by grasping the picking portion 5a.

The picking portion 5a is formed with a groove 6 extending along the longitudinal direction of the temple portion 5.

By fitting the temple portion 5 into the groove 6, the picking portion 5a is mounted to the temple portion 5.

The picking portion 5a is slidable along the longitudinal direction of the temple portion 5. With this arrangement, the picking portion 5a can also be disposed at a desired position.

Returning to FIG. 1, the second frame portion 1c extends from the supporting portion 1a along the upper surface of the lens R and is bent rearward at substantially right angles upon exceeding the lens R, and its tip end has a J-like shape with its tip end being folded back to the inside.

Then, the abutting portion 10 is mounted to the tip end portion of the end portion to project towards the inside.

Here, the abutting portion 10 is mounted to the tip end of the end portion by screw fastening. Accordingly, it can be easily exchanged by detaching the screw.

In case of the eyeglasses 100 according to the first embodiment, the end portion on the other side of the front frame portion (end portion of the second frame portion 1c) has a J-like shape with its tip end being folded back to the inside, the degree of freedom of the tip end on the other side of the front frame portion 1 is improved. Namely, the angle or position can be suitably corrected in accordance with the shape of the side surface of the face and the abutting portion 10 can be reliably abutted against the side surface of the face.

The abutting portion 10 is comprised of a base portion 11 mounted to inside of the end portion on the other side of the front frame portion (end portion of the second frame portion 1c) and a disk-like head portion 12 coupled to the base portion 11 and formed to be larger than the same. In this respect, the disk-like shape might include those having a perfect circular shape or an elliptic shape when seen from the top.

Here, while the material of the head portion 12 is not particularly limited, it is preferably silicone or rubber. In this case, it will be of advantage that the eyeglasses hardly slip when worn.

In the abutting portion 10, the head portion 12 has a relatively large diameter such that the surface area contacting the face, when the abutting portion is abutted against the side surface of the face, becomes large, and consequently, it is possible to reduce pressure loading to the face through the abutment.

The head portion 12 is configured in that its peripheral edge on the opposite side of the base portion 11 has a tapered shape. Therefore, even if the worn eyeglasses 100 are shifted, they will move to slide along the side surface of the face since the peripheral edge of the head portion 12 has a tapered shape. Consequently, it is possible to restrict scratching of the side surface of the face. Further, since there is no directionality when the eyeglasses 100 are shifted in vertical and lateral directions, the hardness of shift will be same in all directions.

In case of the eyeglasses 100 according to the first embodiment, by picking the picking portion 5a with one hand and hooking the temple portion 5 to an ear in a state in which the abutting portion 10 abuts proximate of the temple of the side surface of the face, the eyeglasses can be easily put on and easily put off through reverse operations.

When the eyeglasses 100 are worn, they are fixed on the face at three spots (point A, point B and point C) of the temple portion 5, the pad portion 2 and the abutting portion 10, and it is possible prevent the eyeglasses 100 from being shifted when worn.
